I have had models of the machines made here. Those interested in mechanics will discover for themselves the mechanical defects and unnecessary complications introduced into them. I was working under the supervision of fairly good mechanical engineers, so that defects might not be made too glaring. Some were detected and rectified, but the main defects were not seen, being beyond the powers of calculation of Abdallah; and Hamaida, who could and did see them, was enjoying the pranks which were played. The various ideas I had picked up while associated with Gordon's old corps were now standing me in good stead.
